Client computing devices 80 and computer 70 are only the representation of concept of exemplary computer system.In some examples In, the function combinable described relative to client computing devices 80 and/or computer 70 into single computing device or point In multiple computing devices of the cloth in computer system.For example, cloud computing can be used for the numeral of dental instrument as described herein Design.In one example, the numeral expression of tooth structure is received at a computer at clinic, while using one not With computer such as computer 70 determine the shape and size of dental instrument.In addition, the different computer, such as calculate Machine 70, it may not be necessary to receive whole identical datas so as to its determination shape and size.It can be based at least partially on by history The knowledge that the dummy model of the analysis of case or exemplary case is derived, is represented in the complete 3D for not receiving considered case In the case of, determine shape and size.In such example, the number transmitted between client computing devices 80 and computer 70 According to, or the data of design customization dental instrument are otherwise used for, the whole number dentistry for representing patient can be considerably less than The complete data set of model.

Fig. 4 A and Fig. 4 B show exemplary removable dental instrument 100, and the exemplary removable dental instrument is constructed Into one or multiple teeth for repositioning patient.Similarly, Fig. 5 A and Fig. 5 B show the 3D numbers with the tooth structure of patient The 3D mathematical models for the removable dental instrument 100 that word model 130 is combined.

Removable dental instrument 100 is configured to substantially expose the occlusal surface of the tooth of patient when being worn by the patient. Compared with the removable dental instrument essentially around patient teeth, by providing the occlusal surface of exposure, removable dental instrument 100 can provide plurality of advantages, for example, improve patient comfort, reduce the visuality of dental instrument, reduce because of air between tooth Tartar buildup and patient is allowed to carry out certain journey in the case where not removing dental instrument with caused by saliva stream increase That spends eats or drinks.

Removable dental instrument 100 includes appliance body 102.Appliance body 102 includes effective band 112, effective band quilt It is configured about two of patient an or more teeth (in the example shown, labial teeth).Effective band 112 includes face part 106 and lingual surface part 104.Face part 106 be configured to it is registering with the face side of the tooth surrounded in effective band 112, And the lingual surface side that lingual surface part 104 is configured to the tooth with being surrounded is registering.

Face part 106 and lingual surface part 104 coordinate to form receiver 108.Each receiver 108 represents face part 106 section and the respective segments of lingual surface part 104, the section is configured to when dental instrument 100 is worn by the patient When receive one in the tooth that this is surrounded.Individual reception device 108 can be by the face in the face part 106 of appliance body 102 Lingual surface ridge 107 in face ridge 109 and lingual surface part 104 separates.Lingual surface ridge 107 and face ridge 109 may correspond to what is surrounded Boundary between the adjacent teeth of tooth, but need not extend to any two adjacent teeth it is adjacent between in region.

Receiver 108 at least partially defines the effective band 112 formed by appliance body 102.Effective band 112 is configured with out Put formula end so that when removable dental instrument 100 is worn by the patient, the occlusal surface of the tooth surrounded of exposure patient. For example, when being worn by the patient, the tooth surrounded is positioned in the individual reception device 108 of appliance body 102.Show in shown In example, individual reception device 108 is separated and/or individually limited by least one of lingual surface ridge and face ridge.In other examples In, receiver is subjected to multiple adjacent teeths.

In order to promote the positioning to patient teeth, the corresponding tooth of at least one in the individual reception device 108 with patient Can misalignment compared to relatively.So, appliance body 102 is configured to when removable dental instrument 100 is worn by the patient to trouble The corresponding tooth of person applies revolving force and/or translational force.In identical or different example, appliance body 102 be configured to One or many application translational force in tooth in individual reception device 108.Effective band 112 is also configured to circular Both the labial surface surface of tooth and lingual surfaces are upper to apply opposite power；This compressibility " extruding " can make dental instrument 100 Operation, which is different from, includes other utensils of open surface formula receiver.

Removable dental instrument 100 further comprises anchor log 120.Anchor log 120 prolongs from every side of appliance body 102 Stretch.The band 122 for each including being configured to receive the tooth of patient in anchor log 120, and band 122 is connected to utensil master The stay 121 of body/effective band 112.In the example shown, one or many backteeth of the anchor strap 122 around patient.At some In example, backteeth can be the premolar teeth or molar of patient.The tooth for being worn by the patient and being surrounded when removable dental instrument 100 When being positioned in the individual reception device 108 of appliance body 102, backteeth is positioned in the band 122 of anchor log 120.The quilt of anchor log 120 It is configured so that when removable dental instrument 100 is worn by the patient, keeps the occlusal surface of the backteeth received of exposure patient. In other examples, effective band be configurable to surround one or many backteeth, wherein anchor log be located at effective band it is near in or Distal side.Therefore, anchor log can surround backteeth, labial teeth or combination of the two.

Removable dental instrument 100 can be used as spring appliance, because the lingual surface part 104 of appliance body 102 can be by structure Cause one in generally forward direction into the tooth surrounded or many applying powers.Meanwhile, anchor log 120 is by structure Cause when removable dental instrument 100 is worn by the patient, by being applied in generally rearwardly direction to the backteeth received Reinforce the lingual surface part 104 for carrying out holder with main body 102 applying power in generally forward direction.Alternative specific Implement in (not shown), appliance body can lack lingual surface part or face part so that one or many target tooths are only subjected to One kind in the power being oriented to forward or backward.

In some instances, removable dental instrument 100 may include to catch part, and the seizure part is configured to be attached to patient Intraoral correction anchoring device.Such seizure part can be located on one or both of anchor log 120.

In identical or different example, removable dental instrument 100, including appliance body 102 and anchor log 120, bag Include one or more polymer.For example, removable dental instrument 100, including appliance body 102 and anchor log 120, can be by single Continuous 3D printing part composition.In some specific examples, removable dental instrument 100 (including appliance body 102 and grappling Part 120) the thickness of part can be between about 0.25 millimeter and about 2.0 millimeters thicks, such as between about 0.5 millimeter and about 1.0 Between millimeters thick or be about 0.75 millimeters thick.In some instances, the thickness of the feature structure of removable dental instrument 100 It can change to realize more by the power regulated and controled.In identical or different example, removable dental instrument 100 can be in effective band It is on 112 edge and other spatially including chamfering or fillet.Such chamfering or fillet can improve patient comfort and reduction can Remove the visuality of dental instrument 100.

In other examples, removable dental instrument 100 may include metal parts, and the metal parts is configured to polymerization Thing part provides rigidity to strengthen the power of one or many that removable dental instrument is applied in surrounded tooth.For example, Metal parts may include the filament for the lingual surface part 104 that appliance body 102 is extended through between anchor log 120.Show at some In example, the removable dental instrument of the occlusal surface of exposure is provided when being worn by the patient may include one or more of the other metal portion Part, such as metal are engaged wire jumper, wherein needing larger durability to overcome the stress of high pressure occlusal contact condition.Metal is engaged The demand of wire jumper is attributable to non-conformal patient activity, for example, grit one's teeth or chew.In identical or different example, when being suffered from The removable dental instrument of the occlusal surface of exposure is provided when person wears may include to catch what part was implanted into be connected to patient oral cavity Anchoring device.So, the removable dental instrument of such occlusal surface for providing exposure can provide the combination construction of metal and plastics.

Although plastic components can generally be transparent to reduce visuality, metal parts may include coating or other Dyed layer is to reduce visuality of the removable dental instrument when being worn by the patient.For example, when implanted close to patient teeth The metal parts of positioning may include color white layer, and the metal parts positioned elsewhere can be painted to and generally match patient Intraoral tissue color.

Removable dental instrument 100 can be designed in a digital manner.In some instances, one group of orderly removable dentistry device Tool is designed to set based on a series of numerals to be worn successively.In such example, each removable dental instrument in the group Wear time can be between about 2 weeks and about 12 weeks, such as between about 3 weeks and about 10 weeks or between about 4 weeks and about 8 weeks Between.After the removable dental instrument in the group to have been worn to the prescription time cycle, the removable dental instrument in the group It can be dropped and replace with next removable dental instrument in the group.The design of removable dental instrument 100 can promote this The replacing interval of the removable dental instrument longer cycle in group.For example, because effective band 112 surrounds two in patient teeth Or more, therefore compared with the design of similar dental instrument that wherein each tooth is isolated in individual cavity, when by patient When wearing first, lingual surface part 104 and face part 106 can largely be deflected.Therefore, removable dental instrument 100 can The similar dental instrument design for being designed to be isolated in individual cavity compared to wherein each tooth provides larger amount of tooth It is mobile, and can therefore be designed to be worn by the patient longer time before next dental instrument in by the group is replaced it Cycle.

Although removable dental instrument 100 includes the individual reception device 108 being located in appliance body 102, show other In example, appliance body 102 may not include every restriction individual cavity in the tooth surrounded by appliance body 102 for patient Ridge.In addition, although removable dental section utensil 100 includes single effective band 112, but other examples may include that more than one is effective Band, each effectively band surrounds one or multiple teeth.Although it is not shown in the diagrams, but removable dental instrument 100 and such Other examples optionally include one or more additional stays, the additional stays by this one or more effectively band connection, it is attached Connect or anchor to each other, to tooth or to bonding or be otherwise directly attached to the separate device of tooth.

In the example or other examples, the shape and size of effective band are defined such that each surrounded tooth table The part in face is replicated by the inner surface of removable dental instrument 100, including the face part of such as appliance body 102 The lingual surface ridge 107 in face ridge 109 and lingual surface part 104 in 106.Such duplication can provide conformal in a relaxed state Utensil, while promoting the elastic deformation of removable dental instrument 100 under stress state again, the relaxed state occurs in utensil table At the end of reaching, the stress state occurred in effective week that utensil is expressed when tooth misplaces relative to removable dental instrument 100 During phase.

By replicating the labial surface surface of tooth and the slightly larger part of lingual surfaces, but the part is big not as occlusal surface, The rotation of tooth can be influenceed due to the formation of bigger couple when tooth more misplaces relative to removable dental instrument 100 Turn.By closely replicating the feature structure of tooth in the inner surface of removable dental instrument 100, due to when removable dentistry Utensil 100 can also have couple even if being slightly distorted, therefore removable dental instrument 100 can be particularly effective in the completion stage.Phase Than under, many existing removable utensils, such as spring appliance or the graceful appliance of English, it is to avoid details is carried out in these surfaces Replicate in order to avoid hinder tooth when utensil is moved, thus can be used single utensil that tooth is moved through into larger distance or angle Degree.Remove the details in these utensils and aim to provide the smooth surface that tooth can be slided thereon when utensil is moved, but shortcoming It is, it is much smaller in size by the couple for causing the expected contact point rotated to be formed, so as to cause smaller power and less Utensil expression.

By that analogy, when the inner surface in jaw portion is designed to conform closely with corresponding nut (that is, straight and parallel), Open-end wrench is more effective.But, if the inner surface in jaw portion causes the distance between jaw portion minimum in midpoint for rounding And towards the opening increase at portion at either end, then the power that the contact point in impact wrench between jaw portion and nut is formed It is even, it is parallel and contact the feelings of nut (assuming that there is certain tolerance between jaw portion and nut) in nut apex compared in jaw portion Condition, will have less radius.Similarly, (that is, occlusal gingival is thick for the width of effective band 112 of removable dental instrument 100 Degree) radius for causing couple increase by increase, and this will increase the power that applies during utensil deformation.Although in some cases, Motivation is probably the width that at utmost reduce band for the reason for attractive in appearance or patient comfort (for example, being decreased to always thin Line), but in other cases, it may be advantageous to by the inner surface area and closely for increasing removable dental instrument 100 The feature structure of tooth is replicated, it is subjective attractive in appearance to abandon, to obtain bigger function.

Usable automated manufacturing system such as automated manufacturing system 74 (Fig. 3), is for example calculated based on computer system The mathematical model of removable dental instrument 100 made by machine 70 (Fig. 3), to manufacture removable dental instrument 100.Different In example, it can be used 3D printing or hot forming and finishing (for example being repaired with 5 axle millings or laser cutting) removable to be formed Dental instrument 100.In the case of using 3D printing, 3D directly can be carried out to removable dental instrument 100 by 3D printing system Printing, but in other examples, can be in the removable dental instrument 100 of hot forming above the dental mold using 3D printing formation. In some instances, the tooth of 3D printing can have the occlusal surface of projection or otherwise be different from the tooth of patient, with It is limited in above the dental mold formed using 3D printing and is removed after the removable dental instrument 100 of hot forming from occlusal surface region The demand of material.

In identical or different example, the automation of removable dental instrument 100 or semi-automatic manufacture may include note Modeling, lost-wax casting, 5 axle millings, laser cutting and other manufacturing technologies.Include one or more gold in removable dental instrument Belong in the part such as example of metal occlusion wire jumper, automated manufacturing may include the manipulator manipulation of metal parts, such as metal The manipulator bending of part such as filament.The removable dental instrument of the combination construction of offer metal and plastics it is also possible to use overlapping Injection and/or snap fit technology are manufactured.Such metal parts can also digital form design and by being customized through manipulator The wire of bending is made, is made up of the metal fusible pattern mold of the wax pattern of 3D printing, by " direct metal " 3D printing (including choosing Selecting property laser fusion (SLM) or selective laser sintering (SLS)) it is made or is made up of 3,4 or 5 axle millings of metal derby.As Another option, the stronger part being used in combination for the polymer elements with removable dental instrument can by transparent or The ceramic material for being coloured to tooth color is made.In some instances, metal can be coated with " white " pearly-lustre metal, such as silver, platinum, palladium Or rhodium, to improve aesthetic property.In general, more parts are added and is introduced into joint, manufactured in automation or semi-automation Journey may need certain to assemble after terminating.

So, herein in relation to the removable dental instrument for providing exposed occlusal surface, public technology promotes many not Same configuration.These technologies promote the selection to the tooth through treatment and grappling tooth, while further promoting to power component, grappling Customization size, shape and the selection of placement of part and other feature structures.In addition, also may be selected combination of materials and joint categories with Desired therapeutic effect is provided for patient.
